Final answer:
To maintain garage safety with a parked car, ensure the car is completely turned off to prevent carbon monoxide buildup and have a functioning carbon monoxide detector, along with adequate ventilation.
Step-by-step explanation:
One important safety measure when parking a car in the garage is ensuring that it is turned off completely to prevent carbon monoxide poisoning. Carbon monoxide is a colorless, odorless gas that can be lethal if it accumulates in an enclosed space. It is crucial to have a functioning carbon monoxide detector in the home, which can alert you to dangerous levels of this gas. Additionally, proper ventilation in the garage is essential. This means that any vents and chimneys should be working adequately to allow any harmful gases to escape. During maintenance or when using the vehicle in a confined space, do not leave the engine running to avoid the build-up of toxic fumes. By taking these precautions, you can maintain a safer environment in your garage and protect yourself and your family from potential hazards.
